TRANSOM-LI'FTER.

SPECIFICATION forming part of Letters Patent No. 441,670, dated December 2, 1890.

Application filed May 27, 1890.

To all whom it may concern:

Be it known that I, FREDERICK KAINER, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Transom-Lifters, of which the following is a specification.

My invention relates to a reversible transom-lifter; and the object of my improvements is to provide a transom-litter of such construction that it may be readily applied to either side of the transom, whether suspended axially or hinged to the frame at the bottom or top. This object I have attained in the transom-lifter having its parts constructed as illustrated in the accompanying drawings, in which- Figure l is a front elevation ot' a doorframe and transom in fragment and shows the lifter applied to the different sides. Fig. 2 is a vertical section taken on the line 2 2 of Fig. l, looking toward the right, the dotted lines showing the transom open. Fig. 3 is a fragment of an enlarged vertical section taken on the line 3 3 of Fig. l, looking toward the left. Fig. 4 is an enlarged detail showing in perspective view the lifter-arm detached.

In the drawings, A designates the doorframe.

B is the transom, which is shown in fragment, one part being hinged to the frame at the top and the other at the bottom.

The lifter is composed of abraoket G, having a base-plate adapted to be secured to the door-frame, a box or chamber g for housing a worm-gear F, lixed to a shaft F', which is journaled in said chamber-walls, and two arms g projecting beyond the chamber, and a lifter-arm II provided with a segmental rack H. .Said lifter-arm is pivoted between the ends of the arms g of said bracket by a screw or detachable pin g2, and the construction of the rack and its relation to the lifterarm and the pivotal connection with said bracket are such that said rack can be applied to the Worm, so as to work the arm when projected from either side of said bracket, and the screw or pin being readily detachable enables the person who is to apply the lifter to reverse the lifter-arm in said bracket, so that it will extend up from said bracket on the door-frame, as shown at the leht side of Fig. l, or down therefrom, as shown at the right side, whereby the lifter is adapted to the transom hinged at the bottom or top, and also to be applied on either side of the same. The lifter-arm is curved or bent to one side, so as to extend over and be connected with the transom-sash by means of -a link C, pivarate parts I-I and h, the part 71, being provided with lugs t', adapted to corresponding holes in the part I-I, so that by a clampingscrew i or other equivalent means the said parts may be secured rigidly together in such manner that the part 7L can be readily detached from and reattached to the part I-I, so as to project therefrom on opposite sides in its reversed positions. The part I-I is provided with lateral stops a @,which are adapted to strike the bracket G, and the part h has a stop ZJ at the end, which is adaptedto strike the link C, said stops operating to prevent the transom from being opened too far. The shaft F is provided with a handle E on the lower end for revolving the worm to operate the lifter-arm. The application of the lifter thus constructed to either side of the transom is not conditioned on the manner ot' suspending or hinging the transom, but is made to conform to individual convenience or preference. If the transom is suspended axially, the bracket D maybe connected at either side of the pivot, and by reversing the rack H in the bracket G, or the part h of the arm on the other part, one or both, the lifter is made left-handed or right-handed, and the bracket D on the transom can be placed above or below the bracket G on the doorframe, so as to suit any individual case. One form of lifter is thus adapted to be applied in the various ways which the lordinary circumstances of use require.

I-laving thus described my invention, what I IOO claim, :md desire to secure by Letters Patent, is-

1. In :L transom-lifter and in combination, t bracket, as G, having at base-plate adapted to be secured to a door, a chamber, as g, above the base-plate, a Wormgear fixed in said chamber by :tu operating-shaft jonrnaled therein, a lifter-arm provided With a seg-` mental rack reversibly adapted to said Wormgear and bracket-arms, and means, substantally as shown, for connecting said lifter-arm with the transom-sash, as and for the purpose specified.

2. In a transom-lifter and in combination zt bracket, as G, a worlngear, as F, fixed in said bracket by :t shaft jonrnaled therein, a segmental mok in connection vwith said wormgear, anda lifter-arm made in separate parts, as 1I 7L, Ineens, substantially as desoribed,for readily detaching `and reattaching the parts of said lifter-arm in reversed position, and :L link for connecting said lifter-arm with the sa-sl1,as and for the purpose speced.
